I have a desktop (compac d530s) here with a dvd ram drive installed. First problem was the optical drive was not showing up in explorer and showed up with an error in device manager - got that sorted - now it does not read discs in my computer or explorer - shows up as having a disc inserted but the disc appears empty. However if I open Management Console and check for it in Disk Management - there it is and reading the discs correctly - now if I open My Computer or open explorer it now sees and reads the disc correctly until I eject it. Reinsert disc and back to square one again. I have tried a different opitical drive with same result. My brain has gone numb and I want to hit it (the computer not my brain) with a very big hammer - any help would be a greatly appreciated.

Go into your BIOS and check your drives are set to auto detect, then try fitting a 80 wire IDE cable to the optical drive (if it has a 40 wire on it, this can cause data loss/corruption in certain circumstances). You may have a problem with the drives interface with Windows being stuck in PIO mode (sometimes caused by trying to read bad disks), this may help

Next things could be a ram problem (run Memtest (http://www.memtest86.com/)), XP(?) registry corruption (repair install of OS?), or a motherboard problem (is old enough for Bad Capacitor (http://www.badcaps.net/pages.php?vid=5) problem).

Thanks for those suggestions feersumendjinn apart from doing the memtest everything else seems okay ie capacitors fine, 80 wire cable, auto detect, ultra DMA. Seems to work fine in safe mode. and the hard drive has only 1.7GB free so maybe this is causing a problem

I have seen drives disappear before due to this problem.

Not sure of your O/S so hesitate to give a definitive reply.

Have you tried this?

The full hard drive certainly wont be helping :), doesnt leave much room for your page/swap file, daresay your amount of ram may be small too (those d530sff's only came out with 256MB (I have one ;)), will run much better/faster with more ram (DDR400 will work) and swap file space (do you get "out of memory" errors?).

Have you tried updating to the latest firmware?

Thanks for all your help. I tracked it down to old burning software - Roxio CD Creator and an old version of Nero, once I removed them everything was ok. I had installed an extra 256MB RAM before I started working on this machine because as you rightly pointed out feersum it only came with 256MB. I did the registry - deleting lower and upper registers - that was how I got the drive to show - the problem was the drive although showing a disc was inserted - it read the discs as being empty which I knew they weren't as one was a game disc. Anyway long story shortened - in trying to free up some hard drive space I stumbled across the old cd burning software, removed it and it all works fine now. I installed this drive for the customer back in April and told her she had to free up space on her hard or consider getting a larger one or move her pictures and music to external hard drive. She told me that the drive hasn't worked since I installed it. Yeah Right! Like I wouldn't have checked it after installing. Anyway dropped the computer off to her 7am Sunday morn on my way to see Dad for father's day, when I get back Monday night message on answer phone from her saying the computer is doing funny things now. :groan: aw geeze! Thanks again for all your input.
